赖世雄中级美国英语The Dying Languages

Today, more people than ever before are speaking to each other through satellite television, cellular telephones and computers. This means that people from different parts of the world need to be able to communicate in the same language. That language happens to be English. 
Because of this, experts have predicted that more than half of the world's 6,000 languages may die out in the next century. Already almost all Californian Native American languages are in danger of extinction. They are being swallowed up by English and other language. It is a pity, but that is one of the prices of modernization.
